  • Previous studies have shown that nitrile rubber materials suffer significant changes in physical and chemical properties upon exposures to heat and oxidizing environments. Our work has shown the impact on tensile strength, Elongation and hardness. This is related to the doubles bonds present which undergo scissoring under heat stress causing the increase in crosslink density. This was demonstrated using the Flory Rehner solvent swell principle. The effects on the dynamic properties were also studied as amplitude sweeps at various force levels. Frequency temperature superposition was used to construct G’, G” and Tan delta mater curves.
